Travelers and visitors headed into the Sierra Nevada for the Labor Day weekend are invited to enjoy free downloads of a new mobile phone app for the National Geographic Sierra MapGuide by searching for the “Sierra MapGuide” on your iPhone or Android mobile device.

Sierra Nevada travel tips, restaurants, tourist information and more are now as close as your smartphone thanks to these new apps available for iPhone and Droid devices.

The MapGuide features more than 1,500 destinations provided by local residents and Sierra insiders for everything from iconic Sierra experiences to wine tasting venues, funky cafes, and off-the-beaten-path adventures.

The Sierra Nevada Geotourism MapGuide—sponsored by the Sierra Business Council (SBC) and the Sierra Nevada Conservancy (SNC) working with National Geographic—highlights unique, authentic experiences recommended by local Sierra residents from the Oregon border to south of Sequoia and Kings Canyon National Parks.

It brings together a combination of both the Sierra’s little-known volunteer opportunities, small businesses, hiking trails, and more.

National Geographic project manager Jim Dion said that the online Sierra Nevada map is “living and breathing, and constantly being updated.”

Site visitors can add comments, read what others have posted, and connect to Facebook or Twitter accounts to share what they have found.

In addition, it is never too late to add unique attractions to the MapGuide; nominations are continually reviewed for possible inclusion.
